Sikorsky completes test program, delivers first rugged CH-53 King Stallion heavy-lift helicopter to U.S. Marine Corps
EST PALM BEACH, Fla. The U.S. Marine Corps can start replacing its aging CH-53E Super Stallion military helicopterfleet with new CH-53 King Stallion rotorcraft from Sikorsky, a Lockheed Martin company (NYSE:LMT), which has delivered the first of an expected 200 rotary-wing aircraft for the Marine Corps’ fleet.
The CH-53E first flew in 1974 and entered service with the Marine Corps in 1981. The CH-53K is the new build replacement for the Super Stallion helicopter. The rugged CH-53K helicopter is an all new aircraft with a modern intelligent design intended to ensure reliability, low maintenance, high availability, and enhanced survivability in the most austere and remote forward operating bases.

This first CH-53K heavy-lift helicopter will be stationed at Marine Corps Air Station New River in Jacksonville, North Carolina, where the helicopter will enter into the Supportability Test Plan. U.S. Marines will conduct a logistics assessment on the maintenance, sustainment, and overall aviation logistics support of the King Stallion. This assessment also will validate maintenance procedures with Marine Corps maintainers conducting hands-on care/upkeep of the aircraft. The Supportability Test Plan will ensure readiness and support on the flightline when CH-53K helicopters enter service with the Marine Corps.
Sikorsky expects to deliver its second CH-53K helicopter to the Marine Corps in early 2019.
The CH-53K test program completed the following milestones:
- maximum weight single-point cargo hook sling load of 36,000 pounds (16,329 kilograms);
- forward flight speed of over 200 knots;
- 60 degrees angle of bank turns;
- altitude of 18,500 feet mean sea level (MSL);
- 12-degree slope landings and takeoffs;
- external load auto-jettison; and
- gunfire testing.
“I am very proud of the work accomplished to deliver the most powerful helicopter ever designed into the hands of our Marines,” Deputy Commandant for Aviation Lt. Gen. Steven Rudder says, “and confident in the teamwork and dedication in this program which will carry us to IOC (Initial Operational Capability) next year.”
Sikorsky is preparing its manufacturing facility in Stratford, Connecticut, to house CH-53K production beginning this summer.
The heavy-lift helicopter made its international debut and showcased its maneuverability and advanced fly-by-wire technology during demonstration flights at the recent ILA Berlin Air Show in Berlin, Germany.
